Description

Technical Field

[0001] This utility model relates to the field of measuring equipment technology, specifically to a total station and its adjustment structure. Background Technology

[0002] A total station, also known as a total station electronic distance measuring instrument, is a high-tech surveying instrument that integrates optics, mechanics, and electronics. It is a surveying instrument system that integrates the functions of measuring horizontal angles, vertical angles, distances (slope distances and horizontal distances), and elevation differences. Because it can complete all the measurement work at a station with just one instrument setup, it is called a total station. Before using a total station outdoors, it is necessary to mount it on a tripod. When using it in different geographical environments, the length of the three poles on the tripod needs to be adjusted to adjust the height of the total station.

[0003] In addition to using a tripod to adjust its level, the total station also needs to be precisely adjusted using its base to keep it level. Currently, the existing adjustment method is to maintain the balance of the total station by adjusting the height of the support feet on the base. The principle is to use the rotation of the screw to control the extension or retraction of the support feet. However, this adjustment method is not easy to control the length of the extension or retraction of the support feet, making it difficult for beginners to quickly level the instrument, thus affecting the measurement accuracy.

[0004] To address the aforementioned problems, there is an urgent need for a total station and its adjustment mechanism. Utility Model Content

[0005] The purpose of this invention is to provide a total station and its adjustment structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, a total station and its adjustment structure are provided, including a total station body, wherein an adjustable base is provided at the bottom of the total station body via a rotating shaft;

[0007] The base includes an upper base, a lower base, and a downwardly protruding wedge. The wedge is located at the bottom of the upper base. A groove is provided at the top of the lower base, and a wedge block is slidably connected in the groove. A spherical groove is provided at the bottom axis of the upper base, and a ball bearing is rotatably installed inside the spherical groove. The ball bearing is fixedly connected to the top axis of the lower base by a round rod.

[0008] The cylindrical rod has a fixing member arranged in a ring on its axial surface. The wedge is fixed to the fixing member by a locking bolt. A spring is also installed between the wedge and the fixing member.

[0009] Furthermore, both the upper and lower bases are equilateral triangular structures with rounded apex corners. The top of the upper base is also provided with a calibration bubble. The wedge is arranged in a ring at the apex corner of the bottom of the upper base. The wedge block and the wedge part correspond vertically, and the inclined surfaces of the wedge block and the wedge part fit together.

[0010] Furthermore, the wedge has a through hole, the fastener has a threaded hole, and the locking bolt passes through the hole and is threadedly connected to the threaded hole.

[0011] Furthermore, the slide groove has an inverted T-shaped structure, and the bottom of the wedge is provided with a slider that matches the slide groove. The slide groove is laid from the top corner of the lower base to its axis.

[0012] Furthermore, the spherical ball protrudes from the spherical groove, and the protruding portion does not exceed half of the spherical ball.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] By utilizing the inclined surfaces of the wedge and the wedge block, the wedge moves a smaller distance in the vertical direction when the wedge block moves horizontally, resulting in greater precision. This improves the adjustment effect of the total station and enhances the accuracy of the total station's test data.

[0015] Compared with traditional adjustment methods, the adjustment mechanism in this application is controllable, which is beneficial for beginners. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Those skilled in the art will understand that, unless specifically stated otherwise, the singular forms “a,” “an,” and “described” used herein may also include the plural forms. It should be further understood that the word “comprising” as used in this specification means the presence of the described features, integers, steps, operations, elements, and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0024] Please see Figures 1-4 As shown, a total station and its adjustment structure are provided, including a total station body 1. The bottom of the total station body 1 is provided with an adjustable base 3 via a rotating shaft 2. The total station body 1 can rotate around the rotating shaft 2. The total station body 1 also includes a detection lens, a control panel and a display screen.

[0025] The base 3 includes an upper base 31, a lower base 32, and a downwardly protruding wedge 33. The lower base 32 is used to connect with a tripod support frame and has a threaded hole at its bottom for fixing. The wedge 33 is located at the bottom of the upper base 31. The top of the lower base 32 has a sliding groove 34, in which a wedge 35 is slidably connected. The bottom axis of the upper base 31 has a spherical groove 36, in which a ball bearing 37 is rotatably installed. The ball bearing 37 is fixedly connected to the top axis of the lower base 32 by a round rod 38. The sliding groove 34 extends from the top corner of the lower base 32 toward its axis. When the wedge 35 moves along the sliding groove 34 toward its axis, the distance between the wedge 35 and the wedge 33 increases. Under the action of gravity, the total station body 1 tilts in this direction. Conversely, when the wedge 35 gradually moves away from its axis, the wedge 35 lifts the total station body 1.

[0026] The axial surface of the round rod 38 is provided with a fixing member 4, the wedge block 35 is fixed to the fixing member 4 by locking bolts 5, and a spring 6 is also installed between the wedge block 35 and the fixing member 4;

[0027] In this embodiment, both the upper base 31 and the lower base 32 are equilateral triangular structures with rounded corners. The top of the upper base 31 is also provided with a calibration bubble 7. The wedge 33 is arranged in a ring at the top corner of the bottom of the upper base 31. The wedge block 35 corresponds to the wedge 33 vertically, and the inclined surfaces of the wedge block 35 and the wedge 33 fit together.

[0028] like Figure 2 and Figure 3 As shown, the wedge 35 has a through hole, the fixing member 4 has a threaded hole 8, the locking bolt 5 passes through the hole and is threadedly connected to the threaded hole 8, and the locking bolt 5 also passes through the middle of the spring 6. Tightening the locking bolt 5 will bring the wedge 35 closer to the fixing member 4, and loosening the locking bolt 5 will move the wedge 35 away from the fixing member 4 under the action of the spring 6.

[0029] It is important to note that the slide 34 has an inverted T-shaped structure, and the bottom of the wedge 35 is provided with a slider that matches the slide 34. The slide 34 is laid in the direction from the top corner of the lower base 32 to its axis. The slide 34 and the slider can fix and limit the wedge 35, so that it can only move along the direction of the slide 34.

[0030] In this embodiment, it should also be noted that the axle ball 37 protrudes from the spherical groove 36, and its protruding part does not exceed half of the axle ball 37; at this time, the axle ball 37 can rotate at a certain angle inside the spherical groove 36, but will not detach from the spherical groove 36, thus realizing the connection between the upper base 31 and the lower base 32.

[0031] Working principle:

[0032] First, when installing the total station, fix the total station body 1 on the tripod support frame. Adjust the tripod support frame to keep the total station body 1 relatively horizontal. Then observe the calibration bubble 7 to see if the bubble is in the center position. When it is observed that the total station body 1 is still tilted, adjust the position of the wedge block 35 by tightening the locking bolt 5.

[0033] The adjustment process is as follows:

[0034] Tightening the locking bolt 5 will bring the wedge 35 closer to the fixing part 4; loosening the locking bolt 5 will cause the wedge 35 to move away from the fixing part 4 under the action of the spring 6.

[0035] When the wedge 35 is close to the fixing part 4, the gap between the wedge 35 and the wedge 33 increases. At this time, under the action of gravity, the total station body 1 tilts in the current direction, thereby adjusting the position of the bubble. Conversely, when the wedge 35 is away from the fixing part, the wedge 35 pushes up the wedge 33 in this direction, and the total station body 1 tilts in the opposite direction, and the position of the bubble will also change.

[0036] During the adjustment process, such as Figure 4 As shown, the X direction is the moving direction of the wedge block 35, and the Y direction is the moving direction of the wedge portion 33. Figure 4 As can be seen, the moving distance of wedge 35 in the X direction is significantly greater than the moving distance of wedge 33 in the Y direction, making the moving distance of wedge 33 in the Y direction more accurate, thereby improving the adjustment of the total station.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
